Question 24

How is a BS&W performed for L/O?

Answer 24

(1) Obtain two clean, dry centrifuge tubes and set the tubes in the test tube rack. Shake the oil sample bottle
well. Fill each centrifuge tube with 50 ml of well-shaken sample.
S9086-H7-STM-010
262-5-5
(2) Set the tubes in the test tube rack and fill each tube to the 100 ml mark with PD-680 type II or BIOTEK
Hi-Solv. Cover a cork with a thin plastic film (such as cellophane) so that it can be reused. Rubber stoppers can also be used. Tightly seal each tube and shake for 30 seconds to ensure adequate mixing of the
oil and solvent.
(3) Place the centrifuge tubes securely on opposite sides in the centrifuge. Set the timer for 31 minutes
(allowing 1 minute for the centrifuge to come up to speed and 30 minutes for test time). Whirl at 1500
(±50) RPM. If centrifuge does not have RPM display, confirm actual RPM annually using a tachometer.
(4) Remove the tubes and obtain the percent BS&W by adding the combined water/sediment readings of the
two tubes.
(a) SATISFACTORY:
1. Sediment less than 0.1% AND
2. Combined BS &W less than 0.2%.
(b) WARNING CONDITION:
1. Sediment less than 0.1% AND
2. Combined BS&W from 0.2% to less than 0.4%.
(c) UNSATISFACTORY:
1. Sediment 0.1% and higher; OR
2. Combined BS&W equal to or greater than 0.4%.
(5) At the end of the test, dispose of oily waste in the contaminated oily waste holding tank.
(6) Clean the centrifuge tubes with solvent.
(7) Table 262-5-2 provides the actions that shall be taken for WARNING or UNSATISFACTORY conditions.
